Document Summary

Seven principles for media literacy: all media are texts that can be read, songs, tv shows, radio, movies, all media are representations that help construct our realities, what we watch are planned: edit and location, media are influenced by industrial pressures, most generate revenue and attract advertisers, facebook becomes a place to advertise, media are influenced by political pressures, government can restrict content and ownership, media are impacted by format, all media have their own characteristic and conventions, montage=pass of time, audiences are active participants, we filter meaning through our unique experience, watch the bachelor can know what is sexy to a man, people believe media tell us and influence who we are as a culture. Utopian, dystopian, & mirror views + critiques: dystopian view, medium is bad or was good but it is getting worse, argues that a medium is i. ii. iii. iv.

Part 1: Create Standard Curve

For your standard curve, you need to make up 100 ml of each of the following concentrations of salt.

100 parts per million (ppm)500 ppm1,000 ppm5,000 ppm10,000 ppm

Note: 1 ppm = 1 mg / 1 L.

Step 1: Obtain five 250 mL beakers and label them 1â5.

Use the Equipment selection from the toolbar.Select 250 mL beaker from the dropdown menu.Right-click on beaker and select Label.Label the first beaker 1, and write 100 ppm in the Annotated Note area of the dialog box.Repeat with four more beakers, labeling them with numbers 2â5 and the appropriate concentration in ppm.

Step 2: Add 100 mL of water to each beaker.

Right-click on the beaker and select Water.Select Volume Level of 100 mL.Select Room Temperature water.Click OK.

Step 3: Add the appropriate amount of NaCl to each beaker.

Right-click on beaker; select Chemicals.Select Sodium Chloride (NaCl), the last one in the list.Change units to mg. Be sure to do this or your experiment will not turn out correctly.Add the appropriate amount of NaCl to each beaker (see the table below).To mix, right-click on the beaker and select Stirring Rod.

Step 4: Measure the conductivity of standard NaCl solutions.

Select the conductivity meter from the Equipment menu. Right-click on the conductivity meter and select Conductivity Meter Mode and then ATC mode.Place the conductivity meter in the first beaker.Select both the conductivity meter and the beaker by drawing your cursor over both objects. You have selected both items when you have a single dotted-line box around both. Go to Arrange on the toolbar and select Combine. (Alternatively, right-click and select Combine.) This action actually places the conductivity meter in the beaker.Record the value on the conductivity meter.Measure the conductivity of Beakers 2â5 and record your results.

Part 2: Determine Conductivity of Unknown NaCl Solutions

Step 1: Obtain three 250 mL beakers and label them 1Uâ3U.

Use the Equipment selection from the Toolbar.Select 250 mL beaker from the dropdown menu.Right-click on the beaker and select Label.Label the first beaker 1U.Repeat with two more beakers, labeling them 2U and 3U.

Step 2: Add 100 mL of Unknown Brine Solution 1 to Beaker 1U.

Right-click on Beaker 1U.Select the Chemicals menu.Select 100 ml of Unknown Brine Solution 1U.Click Okay.

Step 3: Repeat Step 2 with Unknown Brine Solutions 2 and 3.

Add 100 ml of Unknown Brine Solution 2 to a beaker labeled 2U.Add 100 ml of Unknown Brine Solution 3 to a beaker labeled 3U.

Step 4: Measure the conductivity of Unknown Brine Solution 1.

Select the conductivity meter from the Equipment menu. Right-click on the conductivity meter, and select Conductivity Meter Mode and then ATC mode.Place the conductivity meter in Beaker 1U.Select both the conductivity meter and the beaker by drawing your cursor over both objects. You have selected both items when you have a single dotted-line box around both. Go to Arrange on the toolbar and select Combine. (Alternatively, right-click and select Combine.) This action actually places the conductivity meter in the beaker.Record the value on the conductivity meter.

Step 5: Measure the conductivity of Unknown Brine Solutions 2 and 3.

Repeat Step 4 with Beakers 2U and 3U.Record the values on the conductivity meter.

Part 3: Make Standard Curve

Now, you need to make a graph with the data from your five known samples of NaCl (Tubes 1â5). You will use this graph (called a standard curve) to determine the concentration of the unknown samples of NaCl (Tubes 1Uâ3U).

Step 1: Using Excel or another graphing program, make a graph of NaCl concentration (ppm) versus conductivity (ÂµS).

When making graphs, you want to have the independent variable on the x-axis and the dependent variable on the y-axis.In this experiment, you know the concentration of NaCl in the first five samples, so concentration is the independent variable and is on the x-axis. You donât know the conductivityâit depends on the concentration. So, conductivity is your dependent variable and is on the y-axis.If you are using Excel, be sure to select a scatter graph. Your graph should be a straight line; if your graph is not a straight line, you may have plotted it incorrectly.Be sure to give your graph a title and label the axes. A good title might be "The Dependence of Conductivity on NaCl Concentration."A sample graph is shown below.

Step 2: Follow the steps below created your graph

Arrange your standard curve data (Tubes 1â5) in two columns. The first one should be NaCl Concentration (ppm), and the second one is Conductivity (ÂµS) as shown below.

Salt Concentration (ppm)

Conductivity (ÂµS)

2.022

2.107

2.213

3.029

100

4.002

Highlight and select all data, including the names of each column.Go to the Insert menu in Excel. Under Charts, select Scatter. Select Scatter with Smooth Lines and Markers. Your graph will pop up.Under Chart Tools, go to Layout.Select Axis Titles, Primary Horizontal Axis Title, Title Below Axis and type in Salt Concentration (ppm).Repeat for the Primary Vertical Axis Title, Rotated Title and type in Conductivity (ÂµS). If you canât find the Âµ symbol, just use uS for your units.Under Chart Tools, go to Gridlines.Under Primary Horizontal Axis, select Major and Minor Gridlines.Repeat for the Primary Vertical Axis..Your graph should be plotted on a line graph.

Part 4: Determine Concentrations of Unknown NaCl Solutions

Now you will use your graph to determine the concentration of the three unknown solutions (1Uâ3U).

Find the conductivity value on the y-axis and go over to the line at that value. Then find the corresponding value on the x-axis. For example, if Sample 1U had a conductivity of 3.25 uS, the concentration of NaCl would be about 60 ppm. Nark it on a line graph

Record the approximate NaCl concentration for each unknown (1Uâ3U).

STEP 3: Write Your Lab Report

Follow the directions above to write your lab report. Write your lab report in Microsoft Word.

In your lab report, include the following information.

In the results section, include all your data and a copy of your graph.

Answer the following questions in the discussion section.

What were the concentrations of the three unknown brine solutions (Samples 1U, 2U, and 3U)?Why do you have to adjust the conductivity meter to a standard temperature? (25 Â°C)Why did the conductivity readings increase as the concentration of NaCl increased?Youâve probably heard of hard water. What makes water hard? How could you use a conductivity meter to determine the hardness of water samples?Calculate the molarity of each of the standard NaCl solutions. Be sure to show your work!Remember the following.The molecular weight of NaCl is 58.44 g / mole.1 ppm = 1 mg / 1 L, so 100 ppm = 100 mg / L, and so forth.Molarity = moles / L.
